Masa-w DANIEL W. HAMAKE R, OF UNION STAR, MISSOURI..

Letters Patent No. 86,068, lated Jamwry 19, 1869.

vThe Schedule referred to in' these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, DANIEL W. HAMAKER, of Union Star, in the county of De Kalb, and State of Missouri, have4 invented new and useful Improvements in Seed and Grain-Drills; and I do hereby declare that the following is a full, clear, and exact description oi' my invention, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon,'of which drawings- Figure l is an elevation of my improved drill.

Figure 2 is a plan of Iy drill when turned upside down.

Figure '3 is a cross-section and plan of dropping pulley.

The natureof my invention consistsin the novel construction of a seed or grain-drill,designed especially for drilling in wheat between rows of standing corn, but which may be used for drilling wheat or other kinds of seed inany situatio'm'the peculiar utility of my improved drill consisting in the ease with which the distance between the drills may be changed to suit any desired kind of work; the security atiorded against any slipping of the drivewheels,whereby the regularity of the dropping of the grain or seed is insured; the whole forming a cheap and eihcient implement of great value,I especially to the farmingfcommunity in new countries, where the land is strong and capable of bearing continuous crops, and the capital of the community too small to afford expensive drills, and where the diflicuity of getting-any repairs. made on complicated machinery is very considerable.

To enable othersV skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A is the main vbeam of my drill, and has mortised in it, near the rear end, the standard Fin the upper end of which is the cross-bar G, the ends of which are secured in the handle's E E, as shown, the lower ends of said handles being secured to `the'heam A, as seen in iig. 2.

The outer beams B B are secured, at their front en s, to the centre beam A, by means of the 'links H which ai s secured to the beam A and the beams B B, bybolts or screws lr fr, u u, as shown. V

. The cross-pieces C C, D, D are of plate-iron, curved, to conform, on each side of the beam4 A, to the shape of the circumference of circles, with their centres at lr fr, or 'at the ends ofthe bolts which secure the links H H to the beam A, as shown, the pieces D D being above, and the pieces O O being below thesaid beam, as seen in fig. l.

The outer beams B B set between these cross-pieces, and are'secured, iu any desired position. by bolts or screws a: z, which pass through holes made inthe pieces vC D, and screw into the beams B B, or passthro'ugh them, and are secured, by nuts, on the opposite side.

vBy having a series of holes made in the pieces O D,

it is readily seen that the distance between the beams B B, and, consequently, the distance between the drills attached to them, maybe changed as desired; and, further, that one beam, B, with its drill, may be brought close to the bearnA, and the otherbeam, B,'with its drill, be secured at some distance from it, so that, where four rows or drills of grain are .to be putin, the 'horse or power attached tothe beam A may travel on or near the centre of the row, in passing up and down the same. l

The standards S S 'are secured in the beams B B, in the position shown, and on their lower ends are secured the teeth U U, which are formed of plate-steel pressed into the formshown.

The brace-pieces P P and Q, Q are shaped in the general form shown, andare secured to the beams B B and inner sides of the teeth U U, and, serve both to brace the teeth U U and carry the axes of the drivingwheels B. R.

These driving-wheels R R kmay be made of sheetmetal, or of. wood with iron tires, and have the sawshaped periphery shown, which prevents any slipping of said wheels,l which would produce irregularities in seeding.

- The crank-axles ole and f g are secured in the wheels R R, -at an angular distance of ninety degrees from each other, andtheir ends are so arranged asto form the axes of the wheels B R, and are pivoted in the brace-pieces P Q, as shown.

The hoppers I I are made in the form shown, and have the covers J J, to prevent the grain or seed from spilling out. l

The dropping-pulleys K K are of circular cross-section, and have the holes k l.: k k arranged on their pe rlphery, as shown.

In th'e lower part of these holes k lc are arranged the screws y y, as seenin iig. 3, the heads of said screws being of the same diameter as the holes k k, and their stems screwing into holes in the pulley K, as shown, from which it is readily seen that the quantity of seed dropped by each hole, 7c, may be varied at pleasure, by raising or lowering the screw y, or that, if desired, one or more of said holes may be prevented from dropping, by raising the head of the screws y up liush with the face of the pulley K.

These dropping-pulleys are hung on shafts ZZ, in the hoppers I I, and on the ends of these shafts, outside of the hoppersyare secured Athe cranks L and O, which are arranged at right angles with each other.

The connecting-rods M M and N N connect these cranks L L and O O with the crank-axles d f and e g, of thedrive-wheels B. R, from which it is readily seen that the rotation of the drive-wheels R R, caused by drawing the machine along lthe ground, will cause a corresponding rotation of the dropping-pulleys K K.

The'y hoppers I I are so constructed as to t closely to the dropping-pullys K K, as seen in the hopper on the right-hand side o lig. 1, and valves a a, of leather or other flexible material, are arranged, as shown, to prevent any grain or seed from'working down between the hoppers I fand dropping-pulleys K.

- The tubes T.'I are arranged with their upper ends in the hoppers I I, and directly under the pulleys KK, and their lower ends extending down behind and nearly n l to the bottom of the teeth U, 'as shown.

It is readily seen, from the foregoing description, that, by applying power to the front end of beam` A, the machine may be drawn along Vthen ground, being guided by means ofthe handles E E, and. that the teeth U'U Will plough a trench for the grain or seed, which will be carried from the hoppers II, by the holes k 'k in the pulleys K K, during the revolution of said pulleys, caused by the wheels R R, as before shown,

and dropped down the tubes T T, each time a hole, k,

' comes opposite the top` of' said tubes, and -that the grain or seed so dropped will be covered by the earth falling over and around the teeth U U, thus drilling in the grain or seed in an effectual manner..

Having thus fully described my invention, d What I claim as new, and desire to secure by Let- 1. The drivefwheels R, when constructed with saW- 'shaped periphery b, substantially as and for Athe purpose herein specified.

2. The peculiar arrangementand combination of the beam A, links H H, cross-pieces C G, D D, and outer beamsB B, each beam, B, having a hopper, with dropping-pulley K, standard and tooth S U, droppingtube T, and driveewheel R, secured thereto, the-several parts being arrangedl and combined, substantially as and for the purpose herein specified. l

3. The adjustable grain or seed-drill, herein described, composed of' the beam A, standard'F, cross-ba1 G,

vhandles E YE, cross-pieoes O C, D D, outer beams B B,

links I'I H, standards' and'teeth S S, U U, droppingtubes T l, brace-pieces P P, Q Q, drive-Wheels R R,

with saw-shaped peripheriesb b and crank-axles el e j' g, conneeting-rodsM M, N N, dropping-pulleys K K, with holes lc k, adjusting-screws y y, and shafts l,l,'with cranks' L 0, L -O,Vh0ppe1's I I, with guard-Valves a a a a and covers J J, the several parts being constructed, combined, and varranged substantially as and forl the purposes herein set forth.

As evidence that I claim the foregoing, I have hereunto set my hand, in' the presence of two Witnesses,

this 10th day of November, A. D. 1868. DANIEL W. HAIWAKER.
